ELECTRIC-WIRE CON N ECTER.

Application flied October 13, 1926.

The principal objectsof the invention are to facilitate the work ofconnecting together the'ends'of electric-wi1'es, andto provide a connecter which'may be easily and quickly handled in securing it to the wires and which will providea very secure means of fastenin and insulating the ends of the wire. w The principal feature of the invention consists in irremovably securing an insulated tube within a tubeof insulating material adapted to receive the-wire ends, said inner tube having means for-securing the wire ends thereiny" In the drawings,"{-'Figure 1 i is a perspective VIGW of my improved connecteq shownat tache'd'to s'ome'wireends; I a

The-custom Fof I connected endswf-electricwires'has been almost completely abandoned 5 and numerous forms of wire connecters have been produced for l securely holding the ends 1 together and insulating same? tion of this type ofconnecten b i In the construction of connedter he'rein illustrated a tube 1 formed of a length of'vulcaniged fibre has its wall swa ed at a point intermediate of its le' n ii to form an annular rib 2 in the inner sur ace.

A metal tube 3 formed with an outwardly extending flange 4 at one end has placed thereover an insulating cover 5 preferably formed of a thin tube of vulcanized fibre the outer diameter of which is preferably the same diameter as the outer diameter of the flange 4. This composite tube is open at both ends and has a threaded openin 5 in one side thereof, which opening is the ull diameter of the interior of the tube and a headless screw 6'is threaded thereinto.

The composite tube is inserted into the tube 1 and the flanged end 4 abuts the rib 2 in the interior thereof and said composite tube is rotatable within the tube 1.

A hole 7 bored in the side wall of the tube 1 is arranged to register with the opening 5 in the composite inner tube to allow of access to the screw so that it can be manipulated to grip the wire ends 8 inserted thereinto.

soldering ai d taping the I -is the purpose oii this in vention to s'implifyanjd improve the construc Serial No. 141.382.

After the inner tube 3 is inserted in place within the tube 1 a disc 9 of vulcanized fibre isv inserted into the end of the tube 1 to abut the end of the; inner tube and the edge 10 of the tube 1 is then swaged over the outer side disc, thus permanently securing the disc in place and irremovably retaining the inner tube within the outer tube.

':In the use of this connecter, the ends of the wires 8, which are to be connected, are twisted together and then inserted into the open end of the. tube 1 so that the insulation of said wires enters the mouth of the tube. Y

The twisted wire ends 8 extend into, the brass tube 3 and the screw 6 is then tightened down upon the wiring, the screw driver being inserted through the hole :7- in the tube 1. iVhen the: screw against the wire ends, the outertube l is then of the inner tubeefl'ectively c0vers th'e open-, ing and completely covers all metal parts. 1
